HINGE.

.SPECIFICATION forming part of Letters Patent No. 692,175, dated January 28, 1902.

u Application filed May 1| 1901. Serial No. 58,337. (No model.)

T ct'ZZ whom it nfl/tty con/067%:

z Be it known that I, FRANK L. BARNICK, a citizen of the United States, residing at- Manhattan borough, New York city, county and State of New York, have invented new and luseful Improvements in Hinges, of which the following is a specification. y

This invention relates to what may properly be called a roller-hinge or roller spring.- hinge,7 which can be made-to allow considerable swing or movement of the door, as when the door is to open to a considerable extent or to swing to or close to the'jamb.

This invention resides in the novel features of construction set forth in the following specication and claims and illustrated in the annexed drawings, in which- Figure 1 is a sectional view of the hinge applied to the door, the latter being closed. Fig. 2 is a section along fr, Fig. 1. Fig. 3 is a section along y y, Fig. 1. Fig. 4 is a view like Fig. 3, the door being open. Fig. 5 shows a modification.

The door 1 is shown .provided with a bridge or door piece 2, adapted to engage a stem 14, so that as the door swings or opensand closes the bridge or connecting piece 2 oscillates the stem. The arms 17, projecting from or rotating with the stem, carry rollers or casters 4 and 4', made to travel on ridges or cam-sur- Two sets or pairs of cams are shown, each pair extending from or forming part of a plate. These plates are indicated at 6 or 6 and are shown as movably seated about the stem or one above the other.

A box 9 is shown with bottom 8 and cap 10,

and the plates 6 6 `have lugs or eyes for the passage or engagement of screws or fastenings 11. Thecams or plates 6 6' being placed in the box and the cap 10 put in place and the bolts or fastenings 11 being made to engage or be secured to the cap and bottom, said bolts will pass through or connect such cap and bottom with plates 6 6 and prevent the latter` from turning, while the passages through movement on said bolts. The cam-plates are thus held from rotary movement and are separated by a series of springs, as at 12, while the rollers 4 and 4' cantravel back and forth over the cam faces or surfaces 5 and 5. As the door opens, the rollers mounting or `running onto the high parts of the cams, the springs are compressed or the cams slid on stem 14, nearer to one another. This springpressure or tendency of the cams to separate closes the door on the release of the latter, the cam-faces rising or separating as the rollers run from the high to the low cam portions.

The spring-pressure can be varied or regulated. For example, springs of greater or less tension caube selected, or the number of springs can be varied-say two springs for `certain pressure and a greater number of springswhen increased tension` or spring is called foror a number of coiled springs can be placed coucentrically or slipped one into the other, as the closed sections of a telescope, so as to secure appreciable stiffness at each individual spring.

The bridge 2 is readily applied, or the door being suitablycut or recessed the bridge and door can be slid or seated one to the other, and thescrews 15 connect or secure the parts. At the front or outer end portion of the bridge the seat or cut in the door can be somewhat widened or a slight degree of play allowed,

,so that the door can be brought to therequired line or sit accurately in `closing posi-L tion when the rollers are at the bottom of the cams. When closed, the door is held shut by the device against the wind or like accidental openings. The bridge and head 14 can also be pinned or secured together, a pin to the starting or bottom point; but having reached the crest of the cam such roller is arrested by stop 16 and has to retreat to return to the cam-bottom.

The cams 5 and 5' of each pair, it is noticed,

are arranged concentrically or one within the Y other--that is to say, each roller while traveling on its own cam will not come into the cir- IOO cnmference or boundary of the path or cam of the other roller of the pair. Say the two cams were of equal diameter or located on the circumference of one and the same circle. Then each roller could not travel more than a halfcircle Without coming onto the cam or path of its companion roller. By the concentric arrangement shown, however, it has been found in practice that cams can be made, say, for example, oftwo hundred and seventy degrees, or, inother words, a self-closing door can be arranged to swing through three-quarters of a circle instead of' only a half-circle, or one hundred and eighty degrees.

The stems or bolts 11, besides holding the cams, also serve as guides on which the cams can slide toward or from one another. A finishing-cap is shown at 18, which can serve to give a finish or neat appearance, but also acts as a sort of cover or protector for cap 10, to which the finishing-cap can be secured by suitable screws or fastenings. The cap 10 is also shown with a flange or rim about the hole or seat-entered by stem 14, and the finish'ing-cap` can be of such thickness as to bring its top face flush with the top of this rim, which latter acts as a sort of protector against water or foreign matter leaking or working into the box. The balls 7 and 7 at the bottom of the stem 14 and at box-bottom 8 allow easy movement or swing of the door.

The box 9 is shown of angular or non-circular form, which insures against rotation of the box when the latter is fitted or sunk into a corresponding seat in the floor or saddle, as that part of the floor or sill receiving the box is sometimes called.

The stem 14 can be one cylindrical piece, to which the cams are pinned or secured; but another practical construction, it has been found, is a stem composed of two parts 14a, Fig. 5, between which the roller-arms 17 swing or are mounted. v

' No claim is made herein to what is shown in United States Patent No. 607,728, granted X, July 19, 1898. y

' f'flfhe cams 5 5 are shown with slight redierent levels.

cesses or concavities, and the rollers 4 4', sitting into these seats or depressions when the door is in closing position, hold the door firmly closed or act asa sort of antirattler t0 prevent the door being vibrated or shaken by the wind or other disturbances. The door is thus what might popularly be called windproof.

It should be noted that the cams are on The inner cam 5 being on a lower level than the outer cam, the arm of the roller running on such outer cam can swing or travel over the top point or shoulder of the inner cam circle when the door is swung open to a considerable extent.

What I claim as new, and desire to secure by Letters Patent, is

1. A hinge comprising a bridge or door piece, rollers made to swing4 or travel with said bridge, means for suitably connecting the rollers with the bridge or door piece, and means provided with cam faces or surfaces for the rollers placed out of the path of one another to allow extended vtravel of the rollers substantially as described.

3. A hinge comprising a bridge or door piece, upper and lower spring-actuated cam faces or surfaces, means for suitably supporting said cam faces or surfaces, and rollers made to move with the door and to travel 0n the respective cam faces or` surfaces, and means for connecting the rollers with the bridge or door piece substantially as described. A
